The thermophysical properties of biological materials depend on the characteristics of each product, such as moisture, structure, and chemical composition, which may vary depending on the process performed [30].
The heat diffusion equation during the freezing process of biological materials can be expressed according to Equation 1, which is the temperature formulation (classical method) for heat transfer [37, 41].

Fig.7 Von Mises stress
Conclusion
Distributed properties of welding residual stress in bridge nodes are researched in the paper, it can be concluded that
(1) The longitudinal welding residual stress distributed closely to the weld joints and the maximum value reaches the material yield strength of Q345qD steel, which has a greater impact on fatigue strength of the structure;
(2) The longitudinal welding residual stress distributed relatively uniform, the maximum value of welding residual stress may occur at any position near the welding joint;
(3) The distributed properties of Von Mises stress is in accordance with the longitudinal direction of the welding residual stress.
